That’s something I noticed a while ago: all podcasters have those huge microphones in front of them - sometimes with a gigantic boom - that wouldn’t look out of place on 1950s TV. But unlike in the 1950s, they’re not trying to hide them, no no: the more visible, the bigger, the better.
I can’t figure out the point of that prop. If I did a podcast, I’d try to unclutter the shot myself.
Studio mics tend to be big, it has its advantages. If your main medium is audio, a huge mic is not a problem.
Podcast is mainly an audio thing with video as an afterthought to reach more platforms.
It isn’t limited to podcasts either. A lot of TV/radio simulcasts have the same setup with big mics for the speakers.
The same thing, those are radio shows with the TV part as an added bonus.
